Piston type sulfur dioxide compressor with pressure alarm adjustment function

Abstract

The invention discloses the field of piston type compressors, and particularly relates to a piston type sulfur dioxide compressor with a pressure alarm adjustment function. The piston type sulfur dioxide compressor comprises a telescopic cover, an alarm device, a bottom plate, a transmission device, a locking and separating device and a detection device, wherein the telescopic cover is inserted into the bottom plate, the detection device is arranged on the side surface of the telescopic cover and the side surface of the bottom plate, the alarm device capable of giving an alarm in a grading mode according to different pressures is arranged above the detection device, the transmission device is inserted below the detection device, the locking and separating device with an automatic popping function is arranged on the side surface of the telescopic cover and the side surface of the bottom plate, and the locking and separating device is connected with the transmission device through a crawler belt. The piston type sulfur dioxide compressor with the pressure alarm adjustment function has the beneficial effects that the structure of a traditional piston type compressor is optimized, so that the piston type compressor has the pressure alarm and emergency treatment functions.

Description

technical field [0001] The invention relates to the field of piston compressors, in particular to a piston sulfur dioxide compressor with pressure alarm regulation. Background technique [0002] Compressor (compressor), a driven fluid machine that raises low-pressure gas to high pressure. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant liquid to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing Compression→condensation→expansion→evaporation (endothermic) refrigeration cycle, the piston compressor generally consists of a shell, motor, cylinder, piston, control equipment (starter and thermal protector) and a cooling system. There are two kinds of cooling methods: oil cooling and natural cooling. In the prior art, due to the aging of some ...
